Pax Americana started in WWII (which killed over 55 million people) and since then, there has been no global conflict of a similar scale. Cf http://www.scaruffi.com/politics/massacre.html http://www.scaruffi.com/politics/massacre.html (top result in DDG). Whether you consider that global relatively free trade is not beneficial to the rest of the world is up to you, but as a citizen of the rest of the world who did benefit I'm quite glad the US did not go isolationist after WWII. Regarding schools, whether the taxpayer's money is used appropriately is another discussion, irrelevant here since Americans, through their elected representatives, chose to spent the money in this way. Funding-wise, last year's budget spent $100bn and this year wants $117bn on the Federal end for "Education, Training, Employment and Social Services" (see link above) of which $69bn in 2015 is for Education (see: http://www.ed.gov/news/press-releases/obama-administration-2015-budget-prioritizes-key-education-investments-provide-opportunities-all-americans http://www.ed.gov/news/press-releases/obama-administration-2...).
